HANTI-FRICTIONVROLLER FOR WAGON-REACH ES.

SPECIFICATION forming part of Letters Patent No. 349,644", datedSeptember 21, 1886.

Applicati. n filed July 12, 1886. Serial No. 207,754. (No model.)

To all whom it may concern.-

Be it known that I, JOHN Q. GRANT, of Longmont, in the county of Boulderand State of Colorado, have invented a new and useful Improvement inAnti Friction Rollers for Wagon-Reaches; and I do hereby declare thatthe following is'a full, clear, and exact description of theconstruction and operation of the invention, so that those skilled inthe art could make and use the same therefrom, refer ence being made tothe annexed drawings, making a part of this specification.

In wheeled vehicles the greatest amount. of wear and friction occurs atthe points of contact of the coupling-pole or reach and the sliding baror sway-bar, and this friction soon wears away the parts, destroyingeither the bar or the reach, or both of them. The object ofmy inventionis to reduce to the minimum this friction of the reach and bar.

To this end my invention consists in the combination of an anti-frictionroller or of anti-friction rollers with the sway-bar and the reach, andalso in certain other combinations and in minor constructions, as willbe hereinafter more fully specified, whereby the results above set forthmay be attained.

In the accompanying drawings, Figure l is a top view. Fig. 2 is a bottomview. Fig. 3 is a view of a portion of the reach with the rollersapplied thereto. Fig. 4 is a section taken on as :20, Fig. 3.

The same reference characters herein refer always to the same or similarparts.

The kingbolt is seen at A, securing the reach or coupling-pole D to thefront axle, O, the hounds being shown at B B, to which is attached inthe usual way the sway-bar or sliding bar H, on which bar is secured inany suitable manner a metallic bearing-plate, H. It is here shownattached by means of screws. The bolster is seen at O and the commonfifth wheel at G.

To the reach are attached two brackets, F F. These brackets are, as seenin Fig. 4, mortised or notched'so as to receive the reach. They may bemade of wood or metal, and in these brackets are journaled, free torevolve, the two anti-friction rollers O C. These rollers are made, asillustrated, of a double conical form, or swelled at the middle andtapering toward bothends. The brackets are attached to the reach bymeans of screw-bolts I I, or even common screws. One obj cct inview inusing these notched brackets is to avoid cutting or mortising the reachitself, and thereby weakening the reach. Another and still moreimportant object is to enable my improved antifriction rollers to beapplied to wagons already in use without any alteration whatever in thewagons themselves or their reaches. My improved anti -friction rollers,along with the brackets, can thus be put on the market as an article ofmanufacture and sold alone.

It is evident that by using my improved rollers the friction occasionedby turning and by all side motions and jostlings will be reduced to aminimum. By making the rollers swelled at the middle I have found byexperiment that the friction is very much lessened, the rollers are verymuch less liable vto bind, and more sure always to revolve or act. Assoon as the sway-bar has run off the swell of one of them the swell ofthe other begins to act. It is evident that the use of one swelled ordouble conical roller alone would be within the scope of my invention;but I prefer two, as more easy of application to the reach and moresatisfactory in action. It might be possible to apply the rollers to theslide or sway bar, but not desirable.

These rollers I make preferably of steel, malleable iron, or other metalbut it is evident that any hard durable substanccsuch as wood, hardrubber, time might bev used. Having thus described my invention, what Idesire to secure by Letters Patent of the United States and claim as newis 1. The combination of a wagon-reach, apair of brackets notched so asto fit the said reach, and in which are journaled so as to be free torotate a pair of rollers with the sway-bar, substantially as and for thepurpose set forth,

2. The combination of the coupling -pole of a wagon, two brackets havingnotches adapted to fit the reach, bolts securing said reach and bracketstogether, and a pair of double conical or centrally-swelled rollers journaled in said brackets with the slide-bar of a Wagon, substantiallyas and for the purpose set forth.

.,3. The combination of a wagon-reach or coupling-pole, a pair ofbrackets secured to said reach or pole and one or more double-c0115 lcal or centrallyswelled rollers supported in 1 In testimony that I claimthe above I have 10 said brackets with a slide or sway bar of a hereuntosubscribed my name, in the presence wagon, substantially as described.of two witnesses, this 7th day of July, A. D.

4. As a new article of manufacture, a pair 1886. of brackets adapted tobe fitted to the reach of a wagon, and one or more double-conical orcentrally-swelled rollers adapted to be journaled therein, substantiallyas described, and for the purpose set forth.

Correction It is hereby certified that Letters Patent No. 349,644,granted September 21 upon the application of J ohn Q. Grant, ofLongmont, Colorado, for an improv in Anti-Friction Rollers forWagon-Reaches, Was erroneously issued to Grant; that the said LettersPatent should have been issued to said Grant and P. Secor anal George T.Dell, of same place, said Seeor and Dell being assignees half interestin said invention; and that the said Letters Patent should be reac' thiscorrection therein that the same may conform to the record of the easePatent Ofiice.
